Well, those are related with the business with have them (even informal 'word of mouth') - they provide you service and to comply with it they call you. It's completely different for unsolicited calls - you don't have any business with them and they don't provide you any service. Having severe fines for the latter should work just fine: they call you, you report them, they receive a fine that put them out of business. It seems to work just fine in Europe so should be doable in US as well. Imagine the "Do Not Call list" but with an angle that everyone are on that list (so no company can call you). You make an appointment with dentist - they ask you for your number and they call you to reschedule, you also provide the phone to the company/technician to install your cable. It feels cleaner
